菜单管理是一套系统中最常见最核心的系统管理模块之一，我把菜单管理分成了2个部分，左边可以管理维护菜单，在菜单的最右侧可以维护每个菜单按钮权限配置
使用element-plus el-tree组件快速开发树形菜单结构，el-tree组件中filter-node-method事件便可以实现树形菜单筛选过滤功能
<template>
<div class="common-tree">
<el-tree
:ref="treeRef"
:data="treeData"
:check-strictly="checkStrictly"
show-checkbox
:accordion="false"
node-key="id"
default-expand-all
:highlight-current="true"
:expand-on-click-node="false"
@node-click="nodeClick"
:filter-node-method="filterNode"
empty-text="暂无数据"
>
<template #default="{ node, data }">
<span class="custom-tree-node">
<span style="margin-right: 15px;">{{ data.name }}</span>
<slot
:data="data"
:node="node"
/>
</span>
</template>
</el-tree>
</div>
</template>
<script>
import { ref, reactive } from 'vue'
import { returnStatement } from '@babel/types';
export default {
name: 'CommonTree',
props: {
treeRef: {
type: String,
default: "treeRef"
},
treeData: {
type: Array,
required: true,
default () {
return []
}
},
checkStrictly: {
type: Boolean,
default () {
return true
}
}
},
setup(props, { emit }) {
const nodeClick = (data, node, tree) => {
emit('nodeClick', data, node, tree)
}
const filterNode = (value, data) => {
if (!value) return true
return data.label.includes(value)
}
return { nodeClick, filterNode }
}
}
</script>使用element-plus el-dialog、el-icon、el-form组件实现菜单新增编辑
el-dialog组件实现弹窗，选择图标功能，父组件通过v-model绑定变量，子组件通过emit('update语法糖实现父子组件属性快速传递
子组件代码：
<template>
<el-dialog width="800px" v-model="visible" title="图标" :before-close="handleClose" >
<ul class="iconUl">
<li v-for="icon in iconList" :key="icon">
<span :class="{'active':choosedIcon === icon}"
@click="chooseIcon(icon)"
@dblclick="confirm(icon)"
>
<el-icon style="width:48px;height: 48px;"><component class="icon" :is="icon" /></el-icon>
</span>
<p>{{ icon }}</p>
</li>
</ul>
<template #footer>
<span class="dialog-footer">
<el-button type="primary" @click="confirm(choosedIcon)">确认</el-button>
<el-button @click="this.$emit('update:visible', false)">取消</el-button>
</span>
</template>
</el-dialog>
</template>
<script>
import { ref, reactive } from 'vue'
import * as IconsModule from '@element-plus/icons-vue'
export default {
name: 'Icons',
props: {
visible: {
type: Boolean,
default: false
}
},
setup(props, { emit }) {
const iconList = ref([])
const choosedIcon = ref(null)
for (var key in IconsModule) {
iconList.value.push(IconsModule[key].name)
}
const chooseIcon = (icon) => {
choosedIcon.value = icon
}
const confirm = (icon) => {
emit('update:icon', icon)
emit('update:visible', false)
}
const handleClose = (done) => {
emit('update:visible', false)
}
return { iconList, choosedIcon, chooseIcon, confirm, handleClose }
}
}父组件代码：
<icons v-model:visible="dialogIconVisible" v-model:icon="menu.icon" />使用element-plus el-table组件实现菜单按钮权限配置
菜单按钮权限配置表格部分代码：
<el-table
ref="resourceTableKey"
:data="resource.tableData.records"
stripe
empty-text="暂无数据"
:header-cell-style="{background:'#FCFBFF',border:'0'}"
style="width: 100%"
@selection-change="resourceSelectChange"
>
<el-table-column type="selection" width="40" />
<el-table-column label="编码" width="80" show-overflow-tooltip>
<template #default="scope">{{ scope.row.code }}</template>
</el-table-column>
<el-table-column label="名称" width="80" show-overflow-tooltip>
<template #default="scope">{{ scope.row.name }}</template>
</el-table-column>
<el-table-column label="请求方式" width="80" show-overflow-tooltip>
<template #default="scope">{{ scope.row.method }}</template>
</el-table-column>
<el-table-column label="请求地址" width="80" show-overflow-tooltip>
<template #default="scope">{{ scope.row.url }}</template>
</el-table-column>
<el-table-column label="操作" width="140">
<template #default="scope">
<el-button type="primary" size="small" @click="resourceEdit(scope.$index, scope.row)"
>修改</el-button
>
<el-button
type="danger"
size="small"
@click="resourceSingleDelete(scope.$index, scope.row)"
>删除</el-button
>
</template>
</el-table-column>
</el-table>

<script>
const resourceTableKey = ref(null)
const resource = reactive({

},
tableData: {

const resourceSearch = () => {

}
const resourceAdd = () => {
dialogEditVisible.value = true
resource.formData = {}
}
const resourceEdit = (index, row) => {
dialogEditVisible.value = true
resource.formData = row
}
const resourceSingleDelete = (index, row) => {
ElMessageBox.confirm('确认删除?',
'确认删除',
{
confirmButtonText: '确认',
cancelButtonText: '取消',
confirmButtonClass: 'confirmButton',
type: 'warning',
})
.then(() => {
resource.tableData.records.splice(index, 1)
})
.catch(() => { })
}
const resourceSelectChange = (selection) => {
resource.selection = selection
}
const resourceBatchDelete = () => {
if (!resource.selection.length) {
ElMessageBox.alert('请选择要删除项！', '提示', { confirmButtonText: '确认', type: 'warning' })
return
}
ElMessageBox.confirm('确认删除?',
'确认删除',
{
confirmButtonText: '确认',
cancelButtonText: '取消',
type: 'warning',
})
.then(() => {
resource.tableData.records = resource.tableData.records.filter(function(items){
return (resource.selection.filter(function(selectionItems){
return selectionItems.id == items.id
})).length == 0
})
})
.catch(() => { })
}
const resourceReturn = { resourceTableKey, resource, resourceEdit, resourceAdd, resourceSingleDelete, resourceSelectChange, resourceBatchDelete }
